Detecting Obscured AGN in the Distant Universe with Spitzer
J. L. Donley, G. H. Rieke, P. G. Perez-Gonzalez +2
We present the results of a Spitzer search for obscured AGN in the Chandra Deep Field-North, using both radio-excess and mid-infrared power-law selection. AGN selected via the form…

Effective Lagrangian Approach to pion photoproduction from the nucleon
C. Fernandez-Ramirez, E. Moya de Guerra, J. M. Udias
We present a pion photoproduction model on the free nucleon based on an Effective Lagrangian Approach (ELA) which includes the nucleon resonances (, N(1440), N(1520), N(15…

Continuous unitary transformations in two-level boson systems
S. Dusuel, J. Vidal, J. M. Arias +2
Two-level boson systems displaying a quantum phase transition from a spherical (symmetric) to a deformed (broken) phase are studied. A formalism to diagonalize Hamiltonians with $O…
